FerroSorp® S series

Pelletized gas purification compound for binding hydrogen sulphide


Ferrosorp® S is based on iron hydroxide and therefore has a very high affinity for H2S. Due to the selective reaction, very high loading rates can be achieved. This makes the FerroSorp® S products particularly economical compared to alternatives.
We offer different grain sizes and products for the optimal solution for your requirements.

Whether 20 ppm or 27,000 ppm H2S, FerroSorp® S reliably cleans your gas to 0 ppm.

Your benefits

  • used and tested for more than 20 years
  • high purification performance
  • high economic value
  • high loading rates for H2S
  • minimised losses in pressure drop due to optimized pellet shape
  • achieves 0 ppm H2S at the outlet


The H2S-containing biogas is passes through a fixed-bed or moving-bed reactor, which is filled with the formed gas purification compund FerroSorp® S. Solid iron sulphide is formed by a chemical reaction of the gaseous hydrogen sulphide with the iron hydroxid, wich can be converted into elemental sulphur in a second reaction.

Dosing air or oxygen causes a continuous regeneration of the gas purification media and ensures maximum loading rates of the FerroSorp® S products.
